Cesare Borgia, the son of Pope Alexander VI, was born in and lived in Rome. Borgia was the comander in chief of the papal army at the peak of his power. Leonardo da Vinci was a patron of Borgia from 1502 to 1503, being given the title "senior military architect, and general engineer". It was Borgia who commissioned da Vinci to create military weaponry/machinery, and da Vinci's design for the machine gun thus was born.
